BBIT

BBIT(2-Butyl-1,2-benzisothiazolin-3-one,below called BBIT)belongs to a kind of isothiazolone ketones,these compounds have a broad-spectrum antimicrobial effect against bacteria, fungi, yeasts and other microorganisms , so it is widely used in industrial circulating cooling water, adhesives, textiles, paint, paper, construction materials, leather, light industry, metal processing oil, plastics, polyurethanes, agriculture and forestry environmental protection and other fields.

First: Characteristics

1、broad-spectrum antimicrobial, effective against Gram-positive bacteria and gram-negative bacteria growth2、effectively inhibit molds, yeasts and algae growth

3、low dosage, efficient, stable, long-lasting

4、free from arsenic and tin5、no VOCs, no odor

6、non-bioaccumulative7、don’t cause any continued pollution to the environment

8、no side effects in the formulation of PU

Compatibility: active ingredient BBIT incompatible with thiol, bleaches, sodium bisulfite and metabisulfite

 

Third: Anti-bacterial properties

BBIT effect can be evaluated by available minimum inhibitory concentration (MICs) . Minimum inhibitory concentrations (MICs) can not explain the usage of the effect, but it showed that the broad-spectrum antimicrobial activity of BBIT. BBIT more emphasis on mildew, effective against fungi erosion, particularly in resisting high- temperature. BBIT is a good choice of fungicide for plastics, polyurethane and other polymer materials; It uses non-specific sterilization methods, so the bacteria can not being resistant .

Four: Typical product application

BBIT is recommended for use in high demanding applications, especially outdoor high UV environments. It can be used for protection and surface anti-bacterial of PVC, silica gel, polyolefin, polyurethane, acrylic resin. Applications include: shower curtain / fabric coating (such as: ski clothing, raincoats, tents) / Vinyl wallpaper and floor / pool substrate / conveyor / soles and uppers / roofing membrane / wire and catheter sheath material / auto accessories (such as: hood, door seals, shock absorbers, steering wheel) / foam material (such as: cushions, gaskets, insulation materials ) / Household Appliances liner (such as: washing machines, refrigerators) / tarpaulins and awnings / antibacterial wall floor paint. 

Five: Instructions

BBIT can be used in liquid, powder or solid antimicrobial product, it also can be used directly on a plastic product or pre-product of plastic to protect them from microbial degradation destruction, or make it a surface antimicrobial effect. BBIT activity effect has been demonstrated under conditions of representative actual use.However, it is recommended that you should use under real-world conditions to test first then determine the most cost-effectiveness of the added amount.BBIT with some chemicals related to the compatibility information and data can be provided with your requirements.

 

Using BBIT percent in the following representative products instructions:       

               

The concentration of an antimicrobial agent to provide the required protection is based on several factors.These factors include: the microbial degradation of the sensitivity of the system, the breadth of microbial invasion, the types of microorganisms, PH value, temperature, humidity, and required protecting time.
